Seeks SKS7300-8GPY4XGS switch disassembly
Time: 2024-01-17
Moduletek Limited Labs recently purchased a Seeks SKS7300-8GPY4XGS switch, which will be briefly disassembled and analyzed to show you its internal structure.
Table 1 Ruoxi SKS7300-8GPY4XGS official description
| Model | SKS7300-8GPY4XGS Managed Ethernet Switch |
| Ports | 8 x 2.5G RJ45; 4 x 10GbE optical ports; 1 x CONSOLE management port |
| Indicator |
LINK/ACT(1-8): Green color corresponds to the rate of 2.5GBPS for devices connected to the port;
Orange color corresponds to the rate of 100/1000M.
LINK/ACT SFP(9-12): Green color means the corresponding fiber optic port is connected.
|
| POWER : Power indicator | |
| Performance | Store & Forward |
| Supports 16K MAC address table depth | |
| Environment | Operating temperature ：0℃~40℃ Storage temperature：-10℃~70℃ |
| Operating Humidity：10%~90%RHRH non-condensing Storage Humidity：5%~90%RH non-condensing | |
| Input power supply | 100-240V |
| Maximum Power Consumption (W) | 30W |
| Noise level (dB) | 40dB(single fan) |
The front panel of the device mainly has eight 2.5G RJ45 interfaces, four 10G SFP interfaces (only 10G is supported), an RJ45 serial port and indicators; the back panel mainly has power jacks, and the exhaust ports are on both sides.

Open the top cover of the switch, you can see that the whole is divided into two parts, one part is the PCB motherboard, integrated with various chips, resistors, heat dissipation and other devices, and the other part is the power supply board. There are 4 transformers in parallel near the front panel of the switch, using GROUP-TEK's HST-48503SCR.

Remove the fan and heatsink, you can see the switch main switch chip (REALTEK's RTL9302C) and memory chip (Samsung's K4B4G1646E-BCMA) underneath the fan; there are two PHY chips under the heatsink next to the transformer, and MAXLINEAR's 4-port 2.5G PHY is used.
